<p>Is your 2017 instance using SSL certificates, and are the certificates self-signed or are they fully signed by a certificate authority. Something I've seen when running NAM 2018 is that when connecting to an instance that only has a self-signed certificate (i.e. Chrome doesn't fully trust it), resources don't load correctly, and I get weird rendering effects similar to you (sometimes CSS doesn't load, sometimes some JS resources don't load breaking functionality). This could have also been the case with 2017, but I don't know as we only switched from HTTP to HTTPS with NAM 2018.</p><p>But when the certificate's signed by a proper certificate authority (i.e. Chrome is happy with the secure connection), everything works fine, and I have no issues with resources.</p>Fri, 29 Mar 2019 00:25:40 GMTLuke BoylingAnswer by Sebastian Krukhttps://answers.dynatrace.com/answers/219831/view.html
<p>I'm running Chrome 73. I have hardware acceleration on. The NAM Server loads without problems. I don't think this is Chrome issue as such. Out of the 290+ users who currently use 18.0.3 version, 56% is on Chrome. </p><p><img src="https://answers.dynatrace.com/storage/attachments/20157-2019-03-28-21-53-38.png"></p><p>Looking at the screenshots attached - it seems like some resources (JavaScript and CSS files) did not load properly or/and the page did not finish loading, e.g., charts did not auto-adjust.</p><p>Now, there are couple of things worth checking (sorry for stating obvious):</p><ul><li>check if resources load correctly</li><li>check if there is anything reported in the JS console</li></ul><p><img src="/storage/attachments/20158-2019-03-28-21-53-41.png"></p><p>Potential problem solutions:</p><ul>
<li>clear browser cache
</li><li>disable any plugins or run in privacy mode</li><li>disable instrumentation (UEM?)</li></ul><p>Let's have a Zoom call to figure that out. Please open a support ticket. </p>Thu, 28 Mar 2019 21:10:50 GMTSebastian Kruk
